VitriGuard is a cryopreservation storage device that is intended for use in vitrification procedures to contain and maintain human 4-8 cell and blastocyst stage embryos.
VitriGuard is a cryopreservation storage device that is intended for use in vitrification procedures to contain and maintain human 4-8 cell and blastocyst stage embryos. The VitriGuard device is composed of a two-piece polystyrene assembly that includes a hexagonal shaped stick and cap. As part of the vitrification procedure, the embryos to be stored are loaded on the tip, also referred to as the leaf, and capped with a pre-cooled cap for subsequent storage following vitrification. The leaf has a trough area for loading. maintaining, and securing the embryos. The stick and cap include a taper design that creates a hermetic seal, forming a closed system. Markings at the stick and the tip of the device provide visual aid for proper device orientation. The device is provided sterile and is for single use only. The VitriGuard has been designed as a cryopreservation storage device to maintain the integrity of human 4-8 cell and blastocyst stage embryos throughout the cooling. storage, and warming processes.

2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the specific numerical sample size (e.g., number of embryos or devices) used for each test. However, it indicates that "various mouse embryos" were used for the Mouse Embryo Survival and Development evaluations.
The data provenance is not explicitly detailed in terms of country of origin. The studies appear to be prospective in nature, as they involve conducting tests on the VitriGuard device according to specified protocols to evaluate its performance.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts
The document does not mention the use of human experts to establish ground truth for the test set. The ground truth for the performance tests (e.g., survival rates, development rates, integrity checks) is established by direct measurement against predefined criteria or by observation of biological outcomes (mouse embryo survival/development).
4. Adjudication Method for the Test Set
Not applicable, as the evaluation methods described are objective measurements or biological assays rather than subjective human assessments requiring adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC comparative effectiveness study was not done. The studies described are performance tests of the device itself, comparing its physical and biological performance characteristics to predefined criteria and to a predicate device.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done
This question is not applicable. The VitriGuard is a cryopreservation storage device, not an AI algorithm. Its performance is evaluated through non-clinical laboratory testing.
7. The Type of Ground Truth Used
The ground truth used for the performance studies is a combination of:
- Direct Measurement/Objective Criteria: For parameters like cooling/warming rates, endotoxin levels, sterility, and physical integrity (e.g., no leakage, no cap expulsion).
- Biological Outcomes Data: Specifically for the Mouse Embryo Assay (MEA), Mouse Embryo Survival Evaluation, and Mouse Embryo Development Evaluation, where the "ground truth" is the observed biological response (e.g., percentage of blastocyst formation, survival rate). These are quantitative biological endpoints.
8. The Sample Size for the Training Set
Not applicable. The VitriGuard is a physical medical device, not an AI/machine learning algorithm that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.
